What is the function of the subway screen door?
1. Prevent passengers from accidentally entering or deliberately breaking into the track area or equipment area, and at the same time can prevent foreign objects from falling into the track area, affecting the normal operation of the train.
2. Prevent passengers from being sucked by the powerful negative pressure generated by the high-speed running of the non-stop passenger train.
3. Isolate the tunnel and the station so that they do not affect each other. On the one hand, it can reduce the load of the station's air conditioning and refrigeration. On the other hand, it can organize the airflow in the tunnel space to reduce the resistance during train movement and keep the air in the tunnel "fresh".
4. The screen door has a sound insulation effect, which can reduce the noise level heard on the platform, especially the noise of the train running on the curve before entering the station.
5 There are some special screen door designs that can provide structural support to the station.
